*                     Disease        No disease
Exposure             7                  124
No exposure        1                   78

Calculate relative risk for this 2x2 table showing the association between wound infection and incidental appendectomy.

The relative risk is (7/(7+124))/(1/(1+78)) which is equal to 4.22. This means someone who is exposed is 4.22 times as likely to develop the disease as someone who is not exposed.

I guess I'll get this started again:
What are the reasons for investigating an outbreak?

I guess I'll get this started again:
What are the reasons for investigating an outbreak?
Control or prevention of the health problem; Opportunity to learn (research opportunity); Public, political, or legal concerns; Public health program considerations; Training
Ento is Lyfe. <3 Ento. <3 Bugs. <3 Insects.
I didn't choose the Bug Lyfe, the Bug Lyfe chose me.

Try again!
to figure out if a common infectious agent/organism cause this outbreak, to prevent additional cases from the same source, to tell how to prevent this problem in the future

Okay (I cheated and read your answer), that makes sense. I guess I'll ask now (although I technically didn't answer correctly). :)
